Suppressing a gene by using its antibody can lead to tooth growth: animal study
Tooth loss is a widespread problem in adults and results in poor quality of life. Currently, solutions to this problem include artificial teeth and implants. But these aren’t as good as “real teeth,” and they don’t markedly improve quality of life. Now, scientists from Japan have made a discovery that can make…

Deriving the piano keyboard from biological principles using clustering
Once upon a time we were creatures in the wilderness and we evolved the ability to hear sounds. Now here's an interesting thing, if you hear a sound of frequency f and others of frequency 2f, 3f, etc then there's a good chance these sounds come from the same object, due to the physical principle of resonance . And so…
